(cl. 24-255) This invention relates to a closure device for folded over on the lines 0b (Fig. 3) to give the bags or other receptacles, intended to contain double fold shownin Fig. 4. The closure device a cereal product, confection or other edible mais nut into place on the folded portion of the bag terial which is likely to deteriorate when exposed so that the body portion ll of the device lies on 5 to air; and the principal object 'of the invention one side of the bag. and the tab l2 on the other 5' is to provide a simple and inexpensive device side. The staple I2 gives the device the necee-- whereby the folded open edges of the has or arv fle bility. tenacity and dur b ityother flexible container may, after being folded The body portion of the device may bear any over, preferably with; double fold, be kept closed suitable printed legend as indicated in Fig. l.
